Description

Finally, according to the invention, it is proposed to support the transverse yoke on the foundation to use a pendulum support whose pendulum axes are horizontal and of which the upper one The pendulum axis crosses the longitudinal axis of the press.

The invention is explained using an exemplary embodiment which is shown in the drawing This shows a side view of a filter press according to the invention.

A pendulum support 2 is arranged on a foundation base 1, which can assume any angular position between two horizontal axes 4 and 5 crossing the press longitudinal axis 3. With the upper end of this pendulum support, a cross yoke 6 is connected that the ends of the two spars 7 rigidly united with one another. On this cross yoke and in its center is a Kugelplonnenlager 8 arranged, over which a head piece 9 can be supported against the cross yoke 6, which in turn rests on lateral lugs 10 on the upper edges 11 of the spars 7 and is consequently angle adjustable within certain limits. The plates 12 of a frame assembly 13 slide on the upper edges 11 of the spars over respective lateral plate attachments 14, while the end of the spars remote from the head piece 6 is equipped with toothed racks 15 on their upper edges 11. An end piece 16, which also slides with lateral lugs 17 on the upper edges of the bars 7, is actuated by a pressure cylinder 18 which is firmly connected to the other ends of the bars 7. At the end piece 16, toothed pinions 19 which are in engagement with the toothed racks 15 are mounted, which are non-rotatably combined with one another, so that the axis of rotation 20 of this pinion always crosses the longitudinal axis 3 of the press at a right angle. In this case, however, the end piece 16 can incline in relation to the horizontal in accordance with the respective shape of the plate pack 13. The pressure cylinder 18 is connected to a support 21 via a hinge axis 22, which also crosses the longitudinal axis 3 of the press at a right angle, so that in the event of a deformation and an inclination of the pendulum support 2, the spars can also assume an inclination relative to the horizontal longitudinal direction 3 of the press.
